To speek or not to speek

All these contacts I have on MSN, and many are online, then why am I not 'chatting to them.. They must be some one I want to talk to since I have them on the list....
I find no matter how badly I want to talk or chat to someone I am always waiting for them to Say Hi first..
What is worse is when Someone Does Say Hi and you say Hi back, maybe have 1 or 2 lines more of greetings then you get that 'awful silence' like you do if you where chatting face to face.. It is the same feeling...
We want to be with others, but when we are we don't know why???

Or is it just me....
